Read it through once

They showed us the noisome cell where the celebrated “Iron Mask”--that ill-starred brother of a hardhearted king of France--was confined for a season before he was sent to hide the strange mystery of his life from the curious in the dungeons of Ste. Marguerite. The place had a far greater interest for us than it could have had if we had known beyond all question who the Iron Mask was, and what his history had been, and why this most unusual punishment had been meted out to him. Mystery! That was the charm. That speechless tongue, those prisoned features, that heart so freighted with unspoken troubles, and that breast so oppressed with its piteous secret had been here. These dank walls had known the man whose dolorous story is a sealed book forever! There was fascination in the spot.
